To all whom it may concern: upon the breaking of a single thread, thus Be it known that I, GEORGE P. BOSWORTH, stopping the rotation of the cap G, and also of Pawtucket, in the county of Providence and of the spool F, which rests upon the friction- State of Rhode Island, haveinventeda new and l disk cl of the cap.
